At first bite, it seems no more than a clever way to boost sales at the expense of a competitor. When a hungry customer walks into a McDonald’s (or within 600 feet of one), they can use the Burger King app to order a Whopper for a single cent. The app will then provide directions to the nearest BK, where the now certainly famished customer can pick it up. The promotion, good until December 12, is called the Whopper Detour. Is it trollish? Sure. Has it worked? Apparently.
